Narrated `Abdullah bin `Umar:Allah's Messenger (ﷺ) said. "While I was sleeping, I saw myself (in a dream) performing Tawaf around the Ka`ba. Behold, I saw a reddish-white man with lank hair, and water was dropping from his head. I asked, "Who is this?' They replied, 'The son of Mary.' Then I turned my face to see another man with a huge body, red complexion and curly hair and blind in one eye. His eye looked like a protruding out grape. They said (to me), He is Ad-Dajjal." The Prophet (ﷺ) added, "The man he resembled most is Ibn Qatan, a man from the tribe of Khuza`a. "
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " بَيْنَا أَنَا نَائِمٌ أَطُوفُ بِالْكَعْبَةِ، فَإِذَا رَجُلٌ آدَمُ سَبْطُ الشَّعَرِ يَنْطُفُ ـ أَوْ يُهَرَاقُ ـ رَأْسُهُ مَاءً قُلْتُ مَنْ هَذَا قَالُوا ابْنُ مَرْيَمَ. ثُمَّ ذَهَبْتُ أَلْتَفِتُ، فَإِذَا رَجُلٌ جَسِيمٌ أَحْمَرُ جَعْدُ الرَّأْسِ أَعْوَرُ الْعَيْنِ، كَأَنَّ عَيْنَهُ عِنَبَةٌ طَافِيَةٌ قَالُوا هَذَا الدَّجَّالُ. أَقْرَبُ النَّاسِ بِهِ شَبَهًا ابْنُ قَطَنٍ ". رَجُلٌ مِنْ خُزَاعَةَ.
